TECHNICAL FIELD

[0001] The utility model relates to a disposable sanitary product field especially, it relates to a capsule core body of enhanced absorption, paper diaper and pull -on. BACKGROUND

[0002] The core body of the prior art disposable sanitary product is usually made of two or more materials as a water absorbing material, one material has good flow guiding effect, such as wood pulp, fluff pulp, etc., another material has good water absorbing effect, such as sap material, therefore, the ratio of the two materials determines the flow guiding and water absorbing effect of the core body, the better the flow guiding effect, the worse the water absorbing effect, and the better the water absorbing effect, the worse the flow guiding effect, therefore, the flow guiding effect and the water absorbing effect usually restrict each other, when a large amount of urine enters in a short time, it is difficult to absorb all the urine in a short time, the urine absorption speed is slow, and urine side leakage is prone to occur. SUMMARY

[0003] Therefore, in view of the above problems, the utility model provides a capsule core body of enhanced absorption. It solves the technical problem of slow urine absorption speed of the core body.

[0004] To achieve the above object, the utility model adopts the following technical scheme:

[0006] Further:

[0007] The diameter of the first water absorbing particles is less than 3mm.

[0008] The number of the first water absorbing particles of the first capsule layer decreases from the middle to the front and back ends.

[0009] The absorption body further comprises a second capsule layer arranged at the bottom of the first capsule layer and a second absorption layer arranged at the bottom of the second capsule layer, the second capsule layer comprising a plurality of second water absorbing particles, the diameter of the second water absorbing particles being greater than 1mm.

DETAILED DESCRIPTION

[0028] The present application will be further described in conjunction with the drawings and specific embodiments.

[0029] Example 1

[0030] Reference Figures 1 to 6 Example 1 provides an enhanced-absorption capsule core, which includes a core 1, the core 1 including an absorbent body 11 and a wrapping layer 12 wrapping the absorbent body 11, the absorbent body 11 including a first capsule layer 111 and a first absorbent layer 112 arranged in sequence from top to bottom, the first capsule layer 111 including a plurality of first water-absorbing particles 2, the diameter of the first water-absorbing particles 2 being less than 3 mm, the number of the first water-absorbing particles 2 of the first capsule layer 111 decreasing from the middle to the front and back ends, the first water-absorbing particles 2 including a water-absorbing inner layer 21 and a water-soluble film 22 wrapping the water-absorbing inner layer 21.

[0031] The diameter of the first water-absorbing particles 2 can also be equal to or greater than 3 mm, which is specifically set according to the situation.

[0032] The first water-absorbing particles 2 can also be uniformly distributed, irregularly distributed, or distributed in other layouts, which is specifically set according to the situation.

[0033] The water-absorbing inner layer 21 is made of sap material or other water-absorbing material, and is usually composed of powdered or granular material, which is specifically set according to the situation.

[0034] The water-soluble film 22 is made of PVA, or other film materials that can be dissolved in water, which is a known material and will not be described here.

[0035] In one embodiment, the height of the core 1 decreases from the middle to the front and back ends. The middle core 1 is thicker due to more urine in the middle, which can improve the absorption rate of the core 1.

[0036] The application also provides a paper diaper based on the above-mentioned enhanced absorption capsule core, which comprises a first liquid-permeable top layer 51, a core 1, and a first liquid-impermeable bottom layer 52 arranged from top to bottom.

[0037] The application also provides a pull-up diaper based on the above-mentioned enhanced absorption capsule core, which comprises a core 1, two elastic waistbands 61 connected to the front and back ends of the core 1, respectively, a second liquid-permeable top layer 62 arranged at the bottom of the core 1, and a second liquid-impermeable bottom layer 63 arranged at the top of the core 1.

[0038] The working mode of embodiment one is as follows:

[0039] The paper diaper or pull-up diaper is worn on the human body. When urine enters the core 1, the urine contacts the first water-absorbing particles 2, causing the water-soluble film 22 of the first water-absorbing particles 2 to dissolve. The high-molecular material of the water-absorbing inner layer 21 contacts water to absorb water. The material density of the water-absorbing inner layer 21 is high, and a large amount of high-molecular water-absorbing material is gathered, which can quickly absorb urine and improve the absorption speed of urine. At the same time, the first water-absorbing particles 2 form gaps between them, which have a certain buffering and blocking effect on urine, preventing side leakage of urine.

[0040] Embodiment two

[0041] Reference Figures 1 to 7 The main difference between embodiment two and embodiment one is that the absorption body 11 of embodiment two further comprises a second capsule layer 113 arranged at the bottom of the first capsule layer 111 and a second absorption layer 114 arranged at the bottom of the second capsule layer 113. The second capsule layer 113 comprises a plurality of second water-absorbing particles 3, and the diameter of the second water-absorbing particles 3 is greater than 1 mm.

[0042] In another embodiment, a plurality of through holes are arranged on the above-mentioned first absorption layer 112.

[0043] The diameter of the above-mentioned second water-absorbing particles 3 can also be equal to or less than 1 mm. The second water-absorbing particles 3 can separate the first absorption layer 112 and the second absorption layer 114, forming a flow guide and buffer space therebetween. The larger the diameter of the second water-absorbing particles 3, the larger the flow guide and buffer space, which is beneficial to the flow guidance of urine, but the thickness of the core 1 also increases accordingly.

[0044] The above-mentioned second water-absorbing particles 3 have the same structure as the first water-absorbing particles 2, and the size can be set to be the same or different, which is specifically set according to the situation.

[0045] After the urine of the embodiment two flows into the first absorption layer 112, it enters the second capsule layer 113, and the urine contacts the second water absorption particles 3, the macromolecular material of the second water absorption particles 3 can quickly absorb the urine, the liquid absorption effect is improved, and the infiltration speed of the liquid is improved.

[0046] Embodiment three

[0047] Reference Figures 1 to 8 The main difference between the embodiment three and the embodiment two is that the first absorption layer 112 of the embodiment three is provided with a plurality of third water absorption particles 4, and the diameter of the third water absorption particles 4 is less than 1mm. The number of the third water absorption particles 4 decreases from the middle to the front and rear directions.

[0048] The third water absorption particles 4 and the first water absorption particles 2 have the same structure, and the sizes can be set to be the same or different, and the specific setting is based on the situation.

[0049] The third water absorption particles 4 can be uniformly distributed, irregularly distributed or distributed in other layouts, and the specific setting is based on the situation.

[0050] The third water absorption particles 4 of the embodiment three can absorb the infiltrated liquid, and the infiltration speed of the liquid is improved.

[0051] The core body 1 of the utility model not only is limited to be used for paper diaper and pull-up diaper, but also can be used for sanitary napkin or other disposable sanitary products.
